Neutron scattering from glycine and deuterated glycine

Dynamics of &#945;-glycine from normal, C-deuterated and N-deuterated samples at 20 K has been investigated through high-resolution neutron-scattering experiments in the energy-transfer range 5-250 meV. Torsional peak of NH<SUP>+</SUP><SUB>3</SUB> is found to be split, an observation made for the first time using neutrons. The torsional potential is seen to be anharmonic. Coupling of other modes to the motion of hydrogen atoms of NH<SUP>+</SUP><SUB>3</SUB> and CH<SUB>2</SUB> is discussed

Dynamics of H₂O in Ba(ClO₃)₂&middot;H₂O

Dynamics of water molecules in Ba(ClO3)2 · H2O has been investigated through high resolution neutron scattering experiments at 6 K in the energy transfer region 5-200 mev. The libration peaks are found to be correlation split, an observation made for the first time using neutrons. The libration potential is seen to be anharmonic. We have now carried out neutron scattering experiments on a powder sample at 6 K on a higher resolution instrument, TFXA (energy resolution about 15 cm-1 at 500 cm-1) at ISIS, Rutherford Appleton Laboratory, U.K., covering the energy transfer (ℏω) region 5-200 mev
